US Patent 11163731 Autobuild log anomaly detection methods and systems

Computing systems, database systems, and related methods are provided for detecting anomalies within a log file. One method involves obtaining log data for test runs executed with respect to a compiled version of executable code for an application platform, filtering the log data based on one or more performance metrics to obtain reference log data, converting the reference log data to a corresponding numerical representation and generating a matrix of the numerical representation. For each line of test log data associated with an update to the executable code, the method converts the line into a numerical representation, determines a difference between the numerical representation and the matrix, and provides an indication of an anomaly when the difference is greater than a detection threshold.
